The serve command now accepts --sql_time_limit_ms for customizing the SQL time
limit.
The publish and package commands now accept --extra-options which can be used
to specify additional options to be passed to the datasite serve command when
it executes inside the rusulting Docker containers.
If someone executes 'select * from table' against a table with a million rows
in it, we could run into problems: just serializing that much data as JSON is
likely to lock up the server.
Solution: we now have a hard limit on the maximum number of rows that can be
returned by a query. If that limit is exceeded, the server will return a
`"truncated": true` field in the JSON.
This limit can be optionally controlled by the new `--max_returned_rows`
option. Setting that option to 0 disables the limit entirely.
